For example, Socrates lived to be seventy years of age in his lifetime. In our world today, there are so many diseases and hazards to our health that, without money for health care, one would not make it anywhere near the age of seventy. 
Also, with the amount of advances in communication, one needs money in order to keep up with what's happening in the outside world. One needs the internet for most communication and even to shop/pay bills. Everyone has a cell phone. Everything is communicated through text message, e-mail, instant message, and tweets. In my personal life, I believe that my mom resembles Socrates in many ways. In one way, she is incredibly independent. She has been a single mother for ten years, works two jobs, and is able to care for myself and my two younger sisters. She also possesses a stubborn attitude in which she won't take no for an answer. Although she does not live a life without material possessions, she does not need many things in her life to make her happy. She also speaks her mind and stands by what she says, no matter what people may say. She's my own modern day Socrates.
